invention relates to printing presses, and particularly to presses vfor applying the designs to felt base Orlinoleum rugs or `other viloor coverings. f

An 'object of myinvention is to provide a means of reducing the time during which a i Vao press is out of service for cleaning.

l Another Object of my invention is to facilitate`thei cleaning of the inking mechanism of aprinting press. ,t-

f Still anotherv object of` my invention-is to n provide a means by which a press ofthe character described may more speedily and conveniently be changed lfrom one design or color scheme to another. 1v g MyV invention.Y possessesv other objects and valuable -f eatures,some of which will kbe set forth in theffollowing description of my invention' which is illustrated in thedrawings forming part of thespecification. It is to be understood that I do not limit myself to the showing vmade by theksaid description" and drawings,` as I may adopt varying forms of w25, my invention within the scope of the claims.

They presses used' for printing felt base floorcoverings are large and bulky, and represent alarge capital investment, not only in themselves] but in' auxiliary equipment, buildings, etc. Obviously if this investment is topayaf proper return it must'be kept in operation during as large a part of the work ingfday as possible.v One of the most serious causes of interruption is the necessity for pe riodically cleaning the mechanism which sup` plies the colors to the* printing blocks. These inkersVwhichjare mountedto roll von a track i' rv.On the press bed,must be scraped andwashed with benzine, and as they areV cumbersome yand heavy it has been the practice in the past to perform this Operationfwith the inker in place Aon the'press.

-- ,1 Broadly, my invention comprises an auxiliary trackl arranged to be connectedV with the track on. the press bed, and means associated with this auxiliary ,trackpermitting the 1nterchangein positionfon the tracks ofV the jpress inker anda second inker Carried by the auxiliary track. By means of thisfarrangement alclean inker maybe substituted for the one on the press with a negligible Vinterruption of operation. The foul inker may then be cleaned at leisure and prepared for instantaneous substitution when the second inker requires cleaning. Y

Referring to the drawings:

Figure 1 is a side elevation of the press and theauxiliary track. Because of the length of the apparatus, portions of the apparatus have been broken away and the figure has been divided in two parts on the line 1-l, Figure l showing the press itself, while Figure 1b shows the auxiliary track and its associated equipment.

base thru the press.

For the purpose of detailed description, I have shown a preferred form of my invention as used in combination with a printingv press of known type, comprising a frame 6 mounted on the wheels 7 to run on the rails '8, which arelaid perpendicular to the lon i tudinal axis of the frame. The press can e moved alongthese rails by the operation of the motor 9 and gear train l1, which meshes with the pinion 12 on theflongitudinal shaft 13 carrying the Wheels 7. The pinion also meshes with a rack 14, laid parallel toy the rails, to provide a positive drive. kBy this mechanism vthe press may be moved into alinement with any of the drying racks (not shown) which are provided for the printed rugs.

Since the press is of known construction, it need merely be pointed out here that the motor 16, operating thru suitable gearing, drives the reciprocating printing heads 17 (of and the Geneva movement 18 which operates the endless conveyor chains 19.l These chains,

carry vpins 21, and the base fabric 22, passing from a roll 23, is pressed onto these pins by the roller 24, the chains carrying it intermittently along the press platen 26.y i

The motor 16 also actuates a pair of reciprocating mechanisms 27, '27, each of which drives an arm 28 which is coupled by a link 29 with theinkers. Dash pots 30, connected with thev arms 28, control and steady themo- Y tion of the inkers.

.Each ofy the latter comprises: a trough shaped ink pot 31 which extends transversely of thev press platen and is carried on flanged Y wheels 32 engaging a track 33 formed in the edge of the platen. Adjacent ythe track is a rack 34. yA'gear 36 meshes with the rack, and,

y thru an intermediate gear 37, drives a gear Lio' 38 fixed to a shaft 39 which is ournaled in the ends of the ink pot and which" carries the inking roller 41. It will be seen that when the reciprocating mechanisms movethe ink pots the rollers are turned to carry the ink to the faces of the printing blocks 42, carried by the printing heads 17. Scrapers 43 rest against the rollers to removeexcess in'k, and ensure a uniform'coating on the printing blocks. The inkers movetogether asa train, each being connected with the next by alink44. Itwill Abe realized that the inkers are heavy andlthat f modate the complete train of inkers. Twoofthese sections are arranged asl a superposed pair in the same vertical plane, one, indicated bythe general reference character 54, being slightly below the level of the press'track, andthe other, indicated by there'ference character 56, slightly above this plane. The third section may be connected' as an extension of either of these tracks by means of switch rails 58, each having dowels 59 in its lower flange for-engaging holes 61 in the cross ties on which it rests. The endsof the vertical flange kof the switch rails are beveled to lform a smooth joint with the rails 5,1. When it is desired to reverse the switch the rails are lifted from their seats, turnedkend for end Y yand interchanged. A- similar switchallows either track 54 or 56 to be connected with the press.

fsa

The'connection with the press is made by a horizontal pair of removable rails 62 which` v are held by dowels A63, similar to .those on the switch rails, on the cross tie 64 at one end and m1 a similar tie or angle 66 secured to the lpress at the other. l e Y y When it is desired to clean the inkers,tlie

tracks.- e f .1 'Y Y 5. In combinationwith a printingrjpress having a track'and ,aplurality ofjinking depress is moved into alinement with the auxiliary track, the rails 62 are placed in posi-` tion, and the switches are set tothe lower track 54. rIhe links 29 are disconnected and y the train of inkers is rolled onto the lower track, after. which the switchesY are reversed and a clean vset of inkers,held ready on'the.

upper track, is moved onto the press. Opera- Y tion of the press may then beimmediately itev sumed, while the foul'y inkers are 'movedvonto' the storage track 57 and cleaned at thej tank GZthere provided for the purpose. After cleaning, the inkers are refilled and moved to the upper track in. readiness for the next change. The clean inkers may, if desired,

Y be lfilled in accordance with anentirely different vcolor scheme, and a change inthedesign Y Y of therug effected in llittle more time than `is required for cleaning. I claim:
